Win 7 update for x64 (KB3021917) crashed my system

Update for Windows 7 for x64-based Systems (KB3021917), has crashed my system 'BSOD'. Forced restart, update reverted changes, pc on reverted changes extremely slow. Optimized system to speed up processes. Helped a bit, but now I am having occasional screen flashes throughout system, internet included. Not that it is affecting the performance of the computer, but it is annoying to say the least.

I have checked out other forums. Not getting the correct answer. Have been to windows/supp....not much help there either.

I would appreciate some help.

Tx, Avamy

PS: the internet is turning into a scary place. Its not like it used to be, just a bit of spyware and some viruses, now its full blown malware, cookie spies, DDoS attacks. Just the other day I shut down Google Chrome as it had been compromised on my side. I have left FB and closed my account there as well. IE, quite frankly does not even operate on my pc. Its a laugh and a half.

This month's updates came in two stages as it looked as if MS had to patch a patch.

Event Viewer or Blue Screen View may have something on your BSOD, but you could use your restore points to prior the original updates, reset IE to defaults then install the updates again - running them twice for the later single update.

I think one of them had been pulled so the newer install may not have the same effect.

If you get another BSOD, post the output of Blue Screen View and the BSOD guys should be able to give you remedial advice.

I have not tried running in safe mode yet, however, I deleted all instances of IE 11, and re-installed IE 10...This is stable, just received a security update for IE 10, so things are rosy there.

Ran AdwCleaner, no Problems and ran RKill. RKill terminated a few infected shortcuts, but indicated that .exe, .bat, and .com associations were fiddled with. Defender disabled. Thats about it. Then Scotty, identified that Automatic updates had been turned off... Sounds like malware. I am using 'Emisoft latest signatures', and a newer effective program called 'Loaris Trojan Remover', but alas, these programs including bitdefender say I am running a sqeaky clean system

Last of all, I have run Belarc Advisor, which has picked some major issues, i.e. oracle Java Critical Security Patches. There are 3 of them, and 2 Critical Windows Security updates. Now the confusing part is that both institutions are telling me that my system is up to date.

There is definitely a problem. About 5 minutes ago, it took me 30+ minutes to write 5 to 6 lines

No it hasn't, This morning, I went into safe-mode with networking, and re-did everything with a few extras; I started with AdwCleaner, then JRT, then RKill, then RogueKiller, then Karpersky's ttdskiller, and finaly CookieSpy. I then cleaned up using CCleaner and Privazer.

Rogue killer came up with 25 Registry issues, and JRT with one issue. So hopefully clean now.

Only issue now I think is the security issues that Belarc Advisory picked up... Win-update says I am covered, and Java says I have the latest platform.

I wrote to Belarc, and they have been kind enough to help me. I have sent a attached report to them, and they are going to see what they can do to help me.

Sudo15, my pc seems to be working fine off line, but if I go to the web, especially gmail, everything slows down; I even have problems closing tabs. I have never really taken notice but since about June 2013, I can only spend 20minutes tops, before the website I am on slows down and even freezes.

I used to spend a lot of time on FB, but I had a internet connection problem, that I could not be on for more than 3mins, before I was knocked off, anyway that is old news, I have since terminated FB.

Google Chrome was another one, it was compromised, so I got rid of it. Now using Firefox and many thanks to you IE 10

I did not install 3021917, as I am suspicious of this kind of "enhancement" and not sure if I need it. It is supposed to diagnose performance issues for upgrade to a newer version of Windows (I have Win 7 x64), but I have no intention of upgrading. When I eventually move to a later version of Windows, it will be on a new computer with that version pre-installed, so I am probably going to put 3021917, and any others similar, into the "hide" bin and forget about it.
